SUMMARY
Male-to-female transgendered persons (MtF) in San Francisco have very high HIV prevalence and incidence. To explore possible sources for these high rates of HIV infection, a rapid needs assessment was conducted using two methods: (1) an interviewer-administered, mostly closed-ended survey with the male partners of MtF persons, and (2) focus groups with MtF persons. Five main themes were evident from the findings: (1) male partners of MtF persons are of all ages, races, sexual orientations, and socioeconomic backgrounds; (2) high-risk sex occurs between MtF persons and their male sexual partners, despite a high level of concern about HIV among both the male and MtF study participants; (3) drug use appears to play a role in unsafe sex between MtF and their male partners; (4) male partners of MtF persons may represent a possible bridge for HIV transmission among different populations, given that they reported sex with male and female partners, as well as transgendered partners; and (5) men engaging in receptive anal sex with MtF partners probably occurs more frequently than reported by the male participants, given the comments of MtF study participants. The results indicate a need for creative, community-based HIV prevention strategies that target the male partners of MtF transgendered persons.
